Constant strings cannot be modified. You can try as follows:
char * str = " This is utterly brilliant ";
char* s = _strdup(str);
printf(">>%s<<\n", s);
str = Trim(s);
printf(">>%s<<\n", s);
free(s);
getch();

Thank you very much.
Using "char * s = _strdup(str);" solved my problem.
Thanks for everyone who tried.

Although this loop works it is slightly flawed in concept. The first part should check whether you have reached the end of the string thus:
while ( *p && isspace(*p) ) ++p ;

Thank you very much.
With the amendments, it works better.

I couldn't understand the following things:
1) What's HANDLE and what function is it doing in this program?
2) When i run the prog, it gives an error message that "Expected initiliazer before int"? How to remove it? I have tried using int main(void) but no effect so far...
#include<stdio.h>
#include<conio.h>
#include<windows.h>
#include<process.h>
// Second Thread Funtion
void ThreadProc(void *param)
//First thread
int main(){
int n,i,val=0;
HANDLE handle;
printf("\t Thread Demo\n");
printf("Enter the number of threads: ");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
val=i;
handle=(HANDLE)_beginthread(ThreadProc,0,&val); //create thread
WaitForSingleObject(handle,INFINITE);
}
return 0;
}
void ThreadProc(void *param)
{
int h=*((int*)param);
printf("%d Thread is running! \n",h);
_endthread();
}
|

|
|
Is the error compile time or run time?
In which line of code does the error occur?
|
|
|
|
|
1) HANDLE represents an instance of the thread. WaitForSingleObject function is waiting on this thread handle until the thread execution is finished.
2) Looks like a semicolon(;)is missing after the declaration of ThreadProc(). Moreover, the #include statements are not complete.

hi, guys
I am newer to MFC and have a question here
----------------
| |
| |
| A |
|_______________|
| |
| B |
|_______________|
Area A and B is two zones, I have a Button in A, and if i click the button, B disappears, showing below, only A; if i click the button again, B shows like above pic
----------------
| |
| |
| A |
|_______________|
my question is how to implenment this function? could you guys give me some idea? thank you very much
|
|
|
|
|
When you design the dialog, make it with area A and B showing.
In the OnInitDialog function of the dialog use SetWindowPos method and set the new height in its cy parameter.
On button click use SetWindowPos again with the full height in the cy parameter.
You can get the current window position using GetWindowRect function.
|
|
|
|
|
You can handle the button click and in the handler, resize the window to appropriate sizes.
|
|
|
|
|
|
thank you, Good Garth, that's exactly what i need 
|
|
|
|
|
might be these functions useful for u.
MoveWindow() or SetWindowPos().

I need a simple HTML parser that can read text from a html file (bold or italic) and tables. I work with Borland Builder C++ 6.
Could you please direct me to some articles/code?
THANKS!

I forgot to mention that the file is from the local hard drive, not from a web server.

Not a problem - just have constructUrl() return a file:// URL.

What about creating your own simple parser using regular expression??

I am not sure about what you are trying to do. What types of operations do you want to undo/redo? You have to give details about your project.
|
|
|
|
|
undo/redo is pretty simple. you need:
1. a data structure that can hold all of the information about any operation the user can perform which can be undone.
2. two stacks
every time the user performs an operation, fill out a structure with all of the information needed to undo that operation, and push it onto the undo stack. clear the redo stack.
to undo, pop the top item off the undo stack, and reverse everything in that item. then push that item onto the redo stack.
to redo, pop the top item off the redo stack, reverse everything in that item. push it onto the undo stack.
